PLAGEN FOR TYPE -WQITRNG MACHINES- York-in the county of New York and State of New York, have invented a new and useful Platen for Type-Writing Machines, of

which'the following is. a specification.

This invention relates to t pe writingmachines, and. more particular y to that class embodying a fiat platen and type-writing mechanism movable longitudinally and transversely thereof for the line and letter spacing of the Writing. c

The object of the invention is to provide a platen with a novel arrangement of worle olding andcarbon-carrying means arranged to be operated by the machine in a manner to facilitate the displacement, replacement, and

4 ,adjustment of the Work.

To this end theinvention contemplates the equipment of a fiat platen constituting the writing-surface with a swinging machine-supporting frame equipped with work-holding and carbonecarrying means and arranged to be elevated or swung up from the platen by anoperating-cam disposed for actuation. by

; the machine when the latter is moved back beyond theswinging structure tea position. above a fixed machine-support located in rear of the printing, area of the platen.

' Subordinate objects of the invention and other-structural characteristics thereof will appear'more fully hereinafter as the succeeding description of the illustrated embodiment of the invention is developed.

In the accompanying drawings, Figure l a perspective view of a type-wrrting-machine .platen' 'equipped in accordance with my inventlon, the machine-supporting frame being shown elevated to facilitate the removal or adjustment of a record sheet or page or the insertion of'a newsheet orpage between the transfer element and the platen.' "Fig. 2 is a longitudinal sectional v1ew of the platen shown in use in connection with. a book, the machine-supporting frame being shown in its depressed position-and thetype-wr1ting machine being indicated more or less diagram- --mati.cally; and Fig; ,3 is a transverse section showing}the' 'manne'r in which the leaf of a book'is' eld upon the platen. by the machinesupporting e frame in proper relation to the transfer-e ment andthe original work-sheet carriedby-the frame.-

Each part is indicated by the same reference character throughout the several views.

For the urpose of this disclosure the invention is illustrated in connection with an ordinary form of flat platen employed in connection with an Elliott-Fisher type-writing machine of the Fisher type. understood, however, that, the invention is to any particular character of type-writing machine. In fact, in certainaspects of the-invention-itis immaterial whether or not a type-writer is employed in connection with the platen, since the invention relates, primarily, to holding means for the work elementor elements and theitransfer element and is" possessed of special utility regardless of the par- It should be drawings, however, is shown acomparatively thin fiat platen 1, adapted to be inserted between the leaves of a book 2, as shown in Fig. 3, and having an extension 3 beyond the printing area. opposite sides of the are vertically-swinging tracks or guides 4, hinged at their rear ends to stationary trackseictions 5, carried by the platen extension3, The swinging traclis 4- are connected adjacent to their front ends by a transverse bar 6 to produce a swinging structure, which-is ordinarily termed a machine-supporting frame. In practice that portion of the platen in advance of the extension 3 is slipped between the leaves of a book, as shown in Fig. 3, with one leaf 'mposed upon the writing-surface of the platen and confined thereon by the machine-sup orting frames Unless it is desired to print irectly u )on the page of the book the frame may also confine a loose work-sheet and a carbonsheet, by means of which a record rinted or otherwise recorded on the sheet will be trans ferred to the )age of, the book. The present invention, iowever, contemplates special provision for the retention of the loose work-' sheet and the transfer element by the mov- Overlyingthe platen l, at

able machine-sup orting frame, whereby when the frame is e evated it it the original Work-sheet and the carbon, so

as to facilitate the displacement, replacement,

or adjustment ofthe underlying leaf or, perchance, an underlying loose record-sheet.

Extending along the inner sides of the tracks will carry wit 'the tracks.

4 are longitudinal Work-holders, preferably defined by longitudinal grooves 7 formed in These grooves are adapted to receive theopposite longitudinal edges of'aloose Worksheet 8 and an underlying carbon elernentor Web 9. The web 9 is wound at its opposite ends upon rotary carriers 10 and 11, carried by the machine-supporting frame and platen, respectively. The carrier 10, upon which the unused portionrofthe carbon is wound, is located Within a transverse slot or opening 12., formed in the. platen, so that the upper edge of the carbonrroll wound on said carrier will: be located. in a slight-l -lower plane than the grooves '7 in the traclts.

The manner. of:- mounting the carrier 10 is not material, but it is preferably carried by bearing brackets 13, secured by thev platen. The carrier-1:1, upon which the used portion ofthe carbon. ortransfierelement is wound from time. to time to present a fresh. or unuseda portion of said element opposite the printing area, ismounted' in brackets 1.4-, pfilldlent from the front ends. ot the tracks, and at theoutenend or the carrieris fixed a thumb.- Wheel. 1:5.to facilitate the winding. of the'earb011, from one carrier or roll: to the other.

The front carbon-rollqis also. dropped; suitithereception 0t theedgesofthe carbon.with

in thegrooves notwithstandin the depressed positions-of the carbon-rolls t eunden ledge of eachof the grooves-is formediwith openings L6 and-1.7;

It will: now-be seen that While the tracks serve toclamp therecord' sheet or leaf upon theplaten they are also. equipped with bold.- ing. and guiding means for the original sheet, as well. as for. a transferelement orweb, thus facilitating the. production of manifold records. Therefore. as the.machine-supporting frame, including. said tracks, is movable toward and from the platen it follows that the described arrangement comprehends ma chine-supporting, work-holding, and transfer means-movable in unison toward. and awa from thewriting-surface. Noclaim is ma e, however, to this subect -.matter broadly, the samebeing describe and cl aimed in'the eopending application of; Stackpole and Laganke, SerialzNo. 52,213, filed-March 21 19.01.

Aside. from the specific construction de scribed, the present invention relates. more particularly to me ans whereby the type-writ- .ingmachine will effect the elevation. of the machine-supportinwframe for the purposeof releasing the under yingvleaf orsheet and for the further purposeof effectin .the separation of the transfer element an athe primary or original work-sheet from-the platen to facilitate the manipulation of the work when the device is emplo ed for manifolding.

Mounted to trave on the tracks or guides 4 to transfer the record from the primary-sheet to a subjacent record: sheet or. leaf. When the record has been completed, the machine ismoved back beyond thevertically-movable machine-supporting frame and. is supported by the stationary track-sections 5 while the work is being manipulated; \lVhen. the. ma chine is moved back froni'the. movable machine-support to the relatively stationary machineesupport, it is. designed toeliiect the automatic elevation ofthe. machine-supporting frame. to the position. shown in Fig 1'. To this end a pair of lifting-arms 16% are pita oted at their-front ends,- as indicated at 20', to the outer sides of the tracks 4 in, advance of their hinges. At points intermediate ofi their ends these arms arepr ovided with. longitudinal slots 24 for the reception of" headed. pins 25, projecting from theopposite-side edges of theplaten to effect a loose pivotal connec'tion between the arms-and platen, permitting the former to swingrfor the purposeof elevating the machine-supporting. frame. The rear ends ofthe arms 19 are oonnectcdby a crossbar. 26, lisposedbelow the-platen.andhaving attached thereto a rearwardly-disposedgcarn arm 27., the endof. which projects upwardly through an opening 28in the platen extension 3 and isdisposed in the-path of the ma chine 18.

When the machine is movedback oven the platen extension, it engages the camrarmfl i, which, it Wlll'bO seen, is located between. the tracks or guides, and: de resses. said: amp to swing the arms 19, and tlius elevate the machineesupportingi frame to. separate the latter, thocarbon element carried-thereby, and the upper. or primary work-sheet from. the platen. When the frame is thus elevated, it willzbe observed that the underlying. sheet or leaf may easily be removed, replaced; on adj usted, the automatic elevation of 'thocarbon obviating the necessity for handlingthe-same and the retention of the frame audits associated parts in. thein elevated positions, en abling the operator to usev bothhands. while manipulatingthe work. It should also beespecially noted. that: the described arrangement, while permitting the automatic-elevation of the movable machiue support and associatedparts, does not necessitate the-depression of the machine from its norm al plane. 011 the contrary, the machine when operating the swinging frame is sustained by manual depression of the a stationary support, so that when the swinging frame drops-backt'o its normal position the two machine-supports are located in the same plane to permit the unimpeded travel of the machine from one to the other. When a pen, pencil, stylus, or other form of record ing instrument is employed in lieu of a typewriting machine, the parts-are manipulated in the manner already described, except,that the elevation of the frame 'is eflected by the or cam-arm 27.

In connection with the invention is shown an automatically-operated work-clamp 29, designed to protect the top edge of the worksheet from contact with the traveling machine. This plate and its operating mechanism constitute no part of the present invention and are described and claimed in Patent No. 747,958 to R. J Fi'shenf t i It may be stated in conclusion that inaddition to the broad subject-matter already disclaimed certain other features embraced by the described arrangement were invented by Stackpole and Laganke'and disclosed in their application before identified and are therefore not claimed herein. Such, for in- -stance, is the broad idea of automatically operating a machine-support, atransfer element, and a work-holder to effect their separation from the platen, also the broad idea of a machine-operated machine-support, Workholder, and transfer element. I

The foregoing description, taken in con.- nection with the drawings, is believed to be sufficient for the purposes, of this disclosure.

Obviously, however, the invention is susceptible of wide variation, and the right'to effect such changes, modifications, and variations of the illustrated structure asmay come fairly'within the scope of the invention is therefore expressly reserved.

What I claim is i 1 The combination with a flat platein of a movable track-frame, a printing-machine mounted to travel on said frame, stationary macl'ii1ie-support in rear of the track-frame, and frame-elevating n'ieans arranged to be engaged. and operated by the printing-ma chine when the latter is moved onto the stationary support from the'track frame.
